In the 'evil rwby parallel universe fanfic', it could be that there is no Beacon Academy as we know it. Instead, there is a place where they train people to be evil enforcers. The relationships between the characters are also twisted. For example, Weiss might be in a power struggle with Ruby, constantly trying to undermine her to gain more control within their evil group. The world itself could be a darker version, with different kingdoms that are all in a state of constant war and strife.
One idea could be that in the parallel universe, the characters have different semblances. For example, Ruby could have a semblance that allows her to manipulate time instead of speed. Another idea is that the kingdoms have different relationships. Maybe Atlas and Vale are bitter enemies instead of allies. Also, the Grimm could be more intelligent and have the ability to form complex societies.
Sure. One popular 'rwby evil parallel universe fanfic' might be 'Dark Reflections'. It twists the characters' personalities in really unexpected ways. The heroes we know become anti - heroes or even villains, which is quite fascinating.
A prevalent theme is also the re - imagining of the power structure. In an evil parallel universe, the Dust and semblance powers might be used for evil purposes. For instance, Ruby's speed semblance could be used to quickly carry out heinous acts. Also, the theme of a corrupted Beacon Academy often comes up, where it becomes a breeding ground for evil instead of a place to train heroes.
The characters could also have different relationships with the Grimm. Instead of fighting them, they could be using the Grimm as tools. They might have some sort of ability to control or communicate with the Grimm. Their backstories would need to be adjusted accordingly. For example, Ruby might have had a traumatic experience that led her to turn evil, like losing someone she loved and blaming the world for it, which then made her decide to take over and reshape it in a more cruel way.
One idea could be a universe where Voldemort won the Battle of Hogwarts. The wizarding world would be in complete chaos and oppression. Harry could be in hiding, trying to find a way to fight back against Voldemort's regime. Another plot could be a world where the Sorting Hat makes different decisions for all the characters. For example, Hermione could be in Slytherin, which would completely change her relationships and the way she approaches magic. Or a parallel universe where magic is known to muggles and they co - exist in a very different way than in the original series.
One possibility is that the relationships between the characters are altered. Weiss might find that in this parallel universe, she has a closer bond with someone she was not as close to in her own universe, like Blake. They would have to adapt to these new relationship dynamics while also trying to figure out how to get back to their own universe if that's their goal.
One idea could be an evil Naruto using his shadow clones in new and devious ways in the RWBY universe. For example, he might send clones to disrupt the huntsmen training, causing chaos. Another could be Naruto teaming up with some of the villains in RWBY due to his newfound 'evil' nature, and together they plan to take over key locations in the RWBY world.
One idea could be a choice where the characters have to decide whether to ally with a mysterious new group in Vale. This new group seems to have some unique powers and resources, but their motives are unclear. It could lead to different story arcs depending on the choice made.
One idea could be a character getting a tattoo that has a hidden power. For example, a RWBY character might get a tattoo that glows when danger is near, like a warning sign. Another plot idea could be a story centered around a tattoo artist in the RWBY universe who creates unique tattoos for the Huntsmen and Huntresses, and each tattoo gives them a special ability or connection to the Dust energy. Maybe a tattoo that allows a character to communicate with Grimm in a strange way, adding an interesting twist to the story.
One idea could be a story where the characters from RWBY have to face a new, extremely powerful Grimm that has unique abilities. This Grimm could be immune to certain types of Dust, forcing the team to come up with creative combat strategies. Another plot could involve a tournament within the RWBY battlefield, where different teams compete not just for victory, but also for a rare and powerful relic. This would add an element of competition and strategy among the characters.
